Gregory Upton filed the foreclosure documents against Craig S. Key and his wife on behalf of Central Oklahoma Federal Credit Union and First Bank of Oklahoma on March 13. The office building in foreclosure is not Key's law office, according to Upton.

The state Attorney General's office, the Department of Agriculture and Oklahoma Highway Patrol executed a search warrant on Key's law office on Thursday. The Attorney General's office said the search warrant is currently sealed and their investigation is ongoing.

According to the Oklahoma Bar Association, Key has no record of previous disciplinary action, but the organization said it cannot confirm or deny any current complaints against him. Complaints do not become public record until disciplinary action is taken.

The attorney was admitted to the Oklahoma Bar Association in 1992.

Key, who was a Lincoln County judge at the time, is known for his controversial decision in the Kelsey Smith-Briggs case. Key returned Kelsey to her mother in 2005. She died 5 months later.

Key defended his decision in a book he authored.

KOCO Eyewitness News 5 went to Key's home on Thursday to ask about the search warrant. A woman answered the door and said, "I'm sorry. The family is not talking right now."
